(CNN)Over 2,000 health care workers in Ghana have tested positive for coronavirus since the beginning of the outbreak in March, according to the Ghana Health Service.
Of those infected, six have died -- five were engaged in active clinical practice, a health adviser for the office of the president said.
"I want to be clear," Dr. Anthony Nsiah-Asare said to CNN on Thursday. "The number of those infected is a cumulative figure and not a number that was a result over a short period of time."
Dr. Patrick Kuma-Aboagye, Director-General of the Ghana Health Service, could not specify exactly how 2,000-plus health care workers became infected but initially, he said, the country faced personal protective equipment shortages that made it difficult for workers to adequately protect themselves.
Since then, he said, the number of those infected has reduced significantly.
"Over 90 percent of the infected has recovered and we now have a sufficient supply of PPE," Kuma-Aboagye said to CNN on Thursday.
He added that he continues to work closely with the public and private health sector to ensure the necessary PPE is provided and has confirmed that proper infection prevention and control measures are routinely conducted at all hospitals.
Ghana President Nana Akufo-Addo announced in an address to the nation that he would extend an incentive to medical professionals "due to the immense dedication and hard work being exhibited by our health care workers."
Each frontline health care worker, he said, would receive an additional 50% allowance added to their basic salary for the next three months.
